Rayson LevelShield · Self-levelling floor systems
Rayson LevelShield SL120 is a solvent-free, two-component, self-smoothing epoxy floor system that delivers a seamless wearing surface with medium to heavy chemical resistance and high mechanical strength.
LevelShield SL120 flows out under trowel, notched rake or roller into a seamless, self-smoothed wearing surface — the standard answer where roller-applied coatings are not enough and a level, joint-free floor is required. Solids content is 100% in both parts, so what goes down is what cures.

| Surface preparation | Substrate must be sound, clean and free of oil, grease, laitance, loose material and bond-inhibiting contaminants. Prepare concrete mechanically (captive shot blasting, milling or diamond grinding); remove weak concrete, open blowholes and voids, and reinstate imperfections with a suitable Rayson repair product. Vacuum all dust. New concrete should be at least 28 days old. |
|---|---|
| Mixing / dilution | Two pre-weighed parts, mix ratio 4:1 (A:B) by weight; mix mechanically for at least 2–3 minutes; pot life up to 20 minutes at 28 °C |
| Application method | Steel trowel, Notched rake, Squeegee and roller, Spike roller to de-aerate |
| Coverage | Approximately 1.6–2.0 kg/m² as a self-smoothing wearing coat, subject to filling grade, porosity, level variation and wastage |
| Application conditions | Minimum substrate temperature 5 °C; substrate moisture content max 5%; minimum mixing temperature +10 °C; cure between +10 °C and +35 °C; prepared substrate pull-off strength above 1.5 N/mm². |
| Drying & curing | At +20 °C: foot traffic 24 h, light traffic 4 days, full cure 7 days. At +30 °C: foot traffic 18 h, light traffic 2 days, full cure 5 days. Recoat window 24 h–2 days at +20 °C (16 h–1 day at +30 °C) |
| Recoat interval | At +20 °C, 24 hours minimum to 2 days maximum; at +30 °C, 16 hours minimum to 1 day maximum. |
| Film / thickness | Self-levelling body coat; nominal thickness set by application rate. |
| Pack sizes | Part A 16 kg / Part B 4 kg per set |
| Storage | Up to 12 months at 5–25 °C in unopened original packaging; protect from direct sunlight. |
| Shelf life | Approximately 12 months unopened, in a cool area. |
